MACHINE FOR SHABPENING BLADES OF SAFETY-RAZORS. I

Specification of Letters Patent.

Patented Sept. 3, 1912.

. Application filed April 25, 1911. Serial No. 623,266.

To all whom it may concern:

Be it known that I, ALBERT E. H1LL, a

'citizen of the United States, residing at Atlanta, in the county ofFulton and State of Georgia, have invented certain new and usefulImprovements in Machines for Sharpening Blades of Safety-Razors; and Ido hereby declare the following to he a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to machines for sharpening blades ofsa-fetyrazors, and the object is to provide improved means for holding theblades in position for being sharpened, and improved means for retain.-ing the blade-holding devices in position.

A further object is the provision of re silient means for supporting theblade-holdin devices.

lhther objects will appear from the following description. r

In the accompanying drawings forming part of this application, Figure 1is a view of the device in front elevation, with portions shown insection. Fig. 2 is a perspective view. Fig. 3 is a top plan view of thepliers for holding the razor blades. Fig. 4- is a side elevationthereof. Fig. 5 is a view in." side elevation of one form offrame forholding the pliers. Fig. 6 is a plan view of the construction shown inFig. 5. Fig. 7 is a section of the machine on the line 7? of Fig. 1 theplier holding frame having,

however, the form shown in Figs. 5 and 6.

Fig. 8 shows means for imparting a. lateral movement to the buttingwheels during rotation.

In carrying out my invention, I provide a framework including a base 10,uprights 11 and 12 and a yoke member 13 connecting the upper portions ofthe uprights. llzlounted in suitable bearings 14 of the uprights areshafts 15 and 16 carrying the pulleys which are provided on theirsurfaces with a suit able covering and constitute bufling wheels. Thesewheels are indicated respectively by the numerals 1'7, 18," 19 and 20.The upper shaft 15 carries a grooved pulley 21, centrally mounted onsaid shaft,. and lower shaft 16 carries a central pulley 22, thesepulleys being driven by means of a suitable belt 24 for operating thebutting wheels. The belt is so arranged that the wheel 21 and thebufling wheels 17 and 18 are driven inadirection opposite to that inwhich the pulley 22 and the wheels 19 and 20 are driven.

In Fig. Sth'ere is shown a modified form of mounting the huffing wheelsin order that they may be gi en lateral movement in addition to therotary movement. This is effected by providing a collar on shaft 16,such collar having a cam surface 26' ar-- ranged to bear against thebeveled end 27 of one of the bearing boxes of the frame. A sprlng 2Qencircles shaft 16 on the opposite side of pulley 22 and tends to returnthe shaft .to its original position after having been shifted by the camacting on beveled end portion 27.

The blade holder consists of a pair of pliers shown in Figs. 3 and at,and having two membe'rsSO and 31 pivoted at 32 and provided with jaws 33and 34, these jaws each having fulcrum members, indicated by 35 and 36.The ends of the members 30 and 31 are enlarged as shown at 37 and 38 andfor-ma ball shaped device which ma be conveniently grasped by the hand.

band. 39 tends around members 30 and 31 members or trunnions 35 and 36are located.

The frames 41 may be connected with the uprights 11 and 12 of theframework of the machine by means of bolts 49. The ends of members 42and l8 are provided with sockets i8, and trunnions and 36 are receivedin these sockets and between the fingers at and Guards l6 are located inthe position shown. This construction permits of the mounting of theblade-holding device in such manner that the blades will bear againstthe periphery of the butting wheels, but will not berigidly held, andmay be manipulated by the operator for the purpose of securing thebestresults.

A further form of plier holding device or frame is shown in Figs. 5 and6, in which fingers 50 and 51 are pivotally connect-ed with each of theside members 52 and 53, and are held in position by separate fiatsprings Z land 55.

What I claim is:

1. In a machine of the class described, a frame, a plurality of axlesmounted therein, a bufling wheel carried by each of the axles, thewheels being in approximate contact at one place, a second frame carriedby the frame first mentioned and between th buff-l ing wheels, thesecond frame comprising a plurality of arms and a central portionconnecting the arms, the connecting portion beingon one side of the lineof approximate contact of the wheels, and the arms extending across theline, and socket members on the ends of the arms, in position to receivea blade-holding device between the wheels, portions of the latterrotating between the blade-holding device, the arms, and the portionconnecting the arms.

2. In a machine of the class described, a frame, a plurality of buflingwheels mounted across the line, and resilient devices form-.

ing, with the ends of the arms, socket members, said resilient devicesbeing secured to opposite sides of the arms and an posit on to receive ablade-holding device and to support the latter bet-ween the adjacentportions of the butting wheels.

In testimony whereof I aflix my signature in presence of two witnesses.
